GAS-QTOVE ATTACEN'I.

Application filed March 19, 1927. Serial No. 1%,743.

The resent invention relates to improvements in gas stoves and hasreference more particularly to an attachment for normally locking thegas cocks in a closed position so that gas will not be permitted toescape through any of the burners of the gas stove when said burners arenot ignited.

Another important object of the invention is to provide an attachmentfor gas burners which is cooperatively associated with the manuallyactuated, thereby permitting any gas cocks and the pilot light controlvalve whereby said locking means will be automatically released frontengagement with the gas cocks when the pilot control valve is or all ofthe gas cocks to be actuated simultaneously spreading the fiamelfrom thepilot light to each of the burners so as to light any or. all of theburners through which the gas may be delivered.

- Another important object of the invention is to provide a gas stoveattachment of the above mentioned character, which is of suchconstruction as to permit the same to be as readily and easily installedwithout necessiattachment of the above mentione tating any materialalterations of the parts of the gas stove with which the attachment isassociated.

A further object is to provide a as stove character'which is simple inconstruction, strong and durable, and further well adapted for thepurposes for which it is designed.

()ther objects and advantages of the invention will become apparentduring the course of the following detailed description.

In the accompanying drawings, formin a part of this application, and inwhich 11 e reference characters designate like parts throughout theviews:

Figure 1 is a top plan view ofthe attachment embodying my inventionshowing the same installed on a gas stove.

Figure 2 is a sectional view taken a proximately on the line 2-2 ofFigure l, coking in the direction of the arrows, for more clearlydisclosin the connectin means between the pilot light control vsfive andthe locking rod. 1

Figure 3 is a sectional view, taken approximately on the line 3 3 ofFigure 1, looking in the direction of the arrows, and

Figure 4 is a detail perspective view of a portion of the lockin rod.

. In the drawings, w erein for the purpose oi illustration is shown thepreferred embodiment of my inventicn, the numeral 1 designates the gassupply pipe which is supported at their-out of the gas stove by thesupporting brackets 2 in the usual manner. Extending rea'rwardly fromthe supply pi 1 beneath the top 3 of the gas stove is t .e torch pipe ortube 4, the inner end of which is disposed upwardly as at 5 and providesa means for delivering gas to the pilot light designated generally bythe numeral 6. As the construction of the pilot light forms no importantpart of the present invention, is detailed description thereof isthought unnecessary.

This pilot light extends through a suitable opening 7 provided thereforin the top 3 of the gas stove and is formed with the as ducts ordischarge openings 8, the same eing disposed radially for-projecting aflame to each of the burners 9 invthe manner well known in the art.

A pilot light cnntrol valve 10 of the conventional construction isassociated with the forward end of the pipe or tube 4 and this valveincludes a button shaped head 11* mounted on the up er end of thevertically movable stem 12 w ereby the same may be manually depressedfor admitting a, supply of gas frpm the main supply pipe 1 to the pilotlight 6 in the manner also well known in the art.-

' In the present instance, I have illustrated four burners, although itis to'be understood that the attachment embodying my invention canbefequally well used with more or less burners. Gas is supplied-to therespec tive burners b means of the pipes iii-which extend from t e mainsupply plpe l and as -sociated with each of these pipes 13 is therotatable gas cock 14. The actuating han-= dle of each gas cock isdesignated b thenw meral 15 and extending lateitdly mm the upper portionof the valve 16 of the gas cock is a pm 17, the purpose of which will behereinafter more fully described.

My attachment com rises an elongated rod 18 which is- 'ourna ed at itsrespective ends in the outermost supporting bracket 2 provided for thesupply pipe 1. Extending rearwardly from the rod 18 and integrallyassociated therewith are the latches 19, the same being adapted forcooperation with the respective laterally extending ins 17, carried bythe rotatable valves of t e respective gas cocks in the manner asclearly shown in Figures 1 and 4 of the drawingsv A nose 1 J ll 20 isformed on the outer end of each of these latch. members and normally thepin 1'? engages the shoulder formed at the juncture of the nose with thebody portion of the latch for locking the rotatable valve 16 of the gascock 141 in a closed position.

The attachment further includes the pro vision of s pair oi? parallelspacedarms 21 which extend rearwardly from the intermediate portion oithe shaft or rod 18 and are rigidly associated therewith. The outer endsof these arms are slotted as indicated at 22. These arms are disposed onopposite sides of the pilot light control valve 10 and the controlbutton 11 of the pilot light control valve is operatively connected tothe arms 21 and the rod 18 in a manner to be now more fully described. Acap isprovided on the vertically movable stem 12 and this cap member isdesignated by the numeral 23. Depending sfrom the sides of the capmember at diametrically opposite points are the fingers 2d, theconstruction of which is more clearly disclosed in Figure 2. A pinextends through the lower end of each finger and is operable Within therespective slots 22 formed in the arms 21 whereby a pin and slotconnection is provided between the inner ends of the arms and the lowerends of the downwardly extending lingers.

Normally the parts are arranged as shown in the drawings and the severalgas cocks are maintained in a closed position.

When any one of the gas burners 9 is to be ignited, the cap member 2 3which is dis posed on top of the depressible head ll of the pilotcontrol valve is pushed downwardly, the pilot light valve will be opento admit a supply of gas trom'thc main supply pipe to the pilotlight 6and this additional supply of gas will eject a flame from the pilotlight to each or the burners and simultaneously with the downwardmovement of ,the cap member 23, the shaft 18 will be rotated, due to thepin and slot connection bea 18 is rotated so as to move in, a downwarddirection, the several latches 19 will move out of engagement with thelaterally extend ing pins 17', thus permitting the rotary valves 16 ofthe respective gas cocks to be actuated whereby to turn on the gas andpermit a supply oi gas to be delivered to the burners. Any one or all ofthe gas coclis may be opened when the shaft 18 is moved in the mannerabove described.

As soon as the pressure is taken as of the cap member 23, the resilientmeans associated with the pilot light control valve will an tomaticsllyreturn the parts to their initial teen the fingers and arms. s fhen theshaft the cocks being accidentally turned on and causing gas to escapethrofigh the burners without being ignited.

The simplicity of my improved attachment enables the same to be readilyand easily installed on a gas stove without necessitating any materialalterations of the stove parts with which the attachment is to beassociated, and furthermore, the device will, at all times, be positiveand ellicicnt in carrying out the purposes for which it is desi ed.

While I have shown the preferred em odiment of my invention, it is to beunderstood that various changes in the size, shape and arrangement ofparts may be resorted to, without departing from the spirit of theinvention or the scope of the appended claims.

What I claim as new is:

1. In combination with a gas stove including the usual rotatable gascocks and the pilot light control valve, of a rod journaled for rotationadjacent the gas cocks, a pin projecting laterally from the rotatablevalve of each gas cock, a series of latches carried by the rod andnormally engaging the respective pins for locking the rotatable valvesof the gas cocks in a closed position, and

means operatively connecting the rod with the pilot light control valvewhereby said rod may be actuated to disengage the latches from therespective pins when the pilot light control valve is actuated to permitsaid gas cocks to be turned on, said aforementioned means comprising acap member carried by the depressible member of the pilot light controlvalve, a. finger extending downwardly from said cap member, an armextending laterally from said rod and operatively connected at its rearend to the lower end of said finger.

2. In combination with a gas stove includthe usual rotatable gas cock,and the deprcssible pilot control valve, of a rod journaled for rotationadjacent the gas cock, a pin projecting lat/erallyfrom the rotatablevalve of the gas cock," a latch carried by the rod and normally engagingthe pin for locking the rotatable valve of the gas cook in a closedposition, and a link and lover connection between thedeprcssible pilotcontrol valve and said rod for disengaging the latch from engagementwith the pin when the pilot light control valve is depressed.

In testimony whereof I afiix my signature.
